Analysis of information sources in references of the Wikipedia article "Chahamanas of Shakambhari" in English language version.
When Gurjara Pratiharas power declined after the sacking of Kannauj by the Rashtrakutkas in the early tenth century many Rajput princes declared their independence and founded their own kingdoms, some of which grew to importance in the subsequent two centuries. The better known among these dynasties were the Chaulukyas or Solankis of Kathiawar and Gujarat, the Chahamanas (i.e. Chauhan) of eastern Rajasthan (Ajmer and Jodhpur), and the Tomaras who had founded Delhi (Dhillika) in 736 but had then been displaced by the Chauhans in the twelfth century.
The period between the seventh and the twelfth century witnessed gradual rise of a number of new royal-lineages in Rajasthan, Gujarat, Madhya Pradesh and Uttar Pradesh, which came to constitute a social-political category known as 'Rajput'. Some of the major lineages were the Pratiharas of Rajasthan, Uttar Pradesh and adjacent areas, the Guhilas and Chahamanas of Rajasthan, the Caulukyas or Solankis of Gujarat and Rajasthan and the Paramaras of Madhya Pradesh and Rajasthan.
